The other days I was thinking on how USB devices such as a scanner, or this video camera works. To my surprise, I see that he mount the device to the FS. But what is it that one will do with the mounted device?
This only applies to some USB devices - namely, those which use the USB Mass Storage driver. Many (though not all) still digital cameras store photographs as standard image files (JPEG, TIFF, etc.) and appear as an external hard drive when you plug them in. You can browse, move, and delete the images through the computer's normal file manager, whether it's the command line, Nautilus, Konqueror, Explorer or Finder.
For scanners (either USB or SCSI), you should install the SANE packages (sane-frontends, sane-backends, xsane, xsane-gimp) included in Fedora Core. You may want to check to see if SANE supports your particular scanner, though.
I'm not familiar enough with video cameras to answer that part.
